I have a GeForce 2 MX 400, Linux Mandrake 8.2 and installed the drivers propery. I can't seem to set my desktop colour depth to 32bit colour, if i do, X stops using the nvidia and reverts to "nv" in the XF86Config-4 file and removes the Load "glx".

The max i can choose is 24bit colour, but then games complain that i need to be using 16bit or higher.
